To all whom it may concern.-

Be it known that I, Orro LADEMANN, of Molkenmarkt- 6, Berlin, 0, Kingdom of Pruse sia, and German Empire, have invented a new andusefulOarving-Machine, (for which I have obtained Letters Patent in Austria-Hungary, No. 2,395 and No. 14,338, bearing date September 3, 1892; in Great Britain, No. 22,518, hearing date December 24, 1891; in France, No. 218,545, bearing date January 8, 1892;"in Belgium, No. 97,841, hearing date January 8, 1892, and in Italy, No. 31,107/65, bearing date January 12, 1892,) of which the following is a specification, reference being had therein to the accompanying drawings.

The object of this invention is a shaping, cutting or reproducing machine which differs from machines such as hitherto constructed in so far that while the latter have their cut ting tools carried by suitable supports and their tracer moved against a firmly fixed work block and pattern, the tracer is fixed in ma- .ohines constructed according to this invention and the tool is arranged to turn upon its own axis only while the pattern, as well as the piece being worked, is fed to the tool by the aid of a table upon which it is fixed.

The great advantage of this machine is that a very rapid rotary motion can be imparted to the cutting tool with a comparatively small expenditure of power and that in consequence of the relative fixity'of the cutting tool and of its slight mobility much more accurate work can be produced than heretofore. Furthermore the small mobility'of the device carrying the cutting tool allows of the constructions of the machine being simplified while increasing its efficiency and durability so as to re duce the repairs to a minimum.

The new cutting, shaping or reproducing machine is illustrated in the accompanying drawings in which 7 Figure 1 is a front view of the same. Fig. 2 is a side'view partly in section on line no a: of Fig. 1. Fig. 3 is a View of a reproducing machine when the working table is moved laterally. Fig.4is a section of the reproducing machine when the work table is moved laterally. Fig. 5 is a front View at an enlarged scale of the pin it connecting the shaft m with ble 0".

the arm 0. Fig. 6 is a side view of Fig.5. Fig. 7 shows on an enlarged scale the articulated connection 'of the bearing with the Weighted arm 0 of the machine, and Fig.8showsasimimoved laterally. By the side thereof the spindles o are inserted through the frame and are provided with suitable adjusting devices I) in which the Workingtool rests. Upon the spindles c are keyed the pulleys f.

The carriage Zcof the machine moves upon the rails j and the axis "In is carried by the lateral part of its frame. 7 The axis m carries the pins at upon which turn the weighted arms 0; these arms being movably connected with the bearings 10 of the axis q of the table 7.

Weights 1" suspended to the table 0" have for their object to maintain the same in such a position that its upper surface may form a horizontal plane.

The arms 0 are located with weights S in order to establish the equilibrium of the ta- This table 7" is provided with devices whereby the model and the Worked pieces are held in position; these devices are not shown in the drawings. A forward and backward motion can be imparted by means of the wheels j rolling upon the rails j to the table 1" which carries the worked pieces 25 and the pattern 25. The working. table 1' receives a vertical motion-from the weighted arms 0 the axis at turning on its bearings Z. The lateral motion of the working table and of the pieces being placed results from the weighted arms 0 being placed upon the pins n of the axism and from the movable connectionof the bearings 19 upon the weighted arms 0. The table ismoved by hand.

g The mode of operation of the machine is such that after the spindles c and their tools 6 are set in rotation/the table carries .the pieces t to be worked and the pattern t is'fed to the tools the said pieces being then cut correspondingly to the contacts of the tracer with the model or pattern t.

What I claim, and desire to secure by Letters Patent of the United States, is

1. In a carving machine, the tracer mounted in a fixed position in the main frame, in combination with a supporting frame or carriage movable horizontally under said tracer, and a working table mounted on said traveling support, by connections which provide for vertical movement thereof, and adapted to receive and hold the pattern and piece to be operated upon, substantially 'as described.

2. In a carving machine, a tracer fixed in the frame of the machine, in combination with OTTO LADEMANN.
